摘要
Abstract
Methyl oleate was an important chemical material,but the production was restricted by equipment corrosion,environmental pollution and low conversion.Non-catalyst two-step method was offered to synthesize methyl oleate.Firstly,oleic acid was reacted with thionyl chloride to obtain active oleoyl chloride,followed by the alcoholysis of oleoyl chloride with methanol to obtain methyl oleate.The kinetic equations for the two reactions were established.The kinetic experiments were carried out at 293,298,303,308,313 K,respectively.The experimental data at different temperatures were analyzed by the integral method.The results show that two steps of methyl oleate synthesis are a second order reaction both and the reactions follow tetrahedral mechanism.The frequency factors are 2.76 ×1019 and 4.03 ×1018,and activation energies are 121.6 ,115.2 kJ/mol respectively for two reactions,which are obtained from the reaction rate constants at different temperatures by using the Arrhenius equation.The calculation data of the kinetic equations are in good agreement with the experimental data at 293-313 K,which shows that the kinetic equations are reliable and reasonable.It provides the basic data for the industrial development of methyl oleate.关键词
